Be honest with your parents! Tell them that all of your friends are going away on this trip and you don't want to miss out on the experience. Also, be sure to offer to come home for a weekend or a different break. Tell them that, while you're away with your friends, that you will call them and/or FaceTime them everyday and send them photos from your trip. Depending on how long your break is and depending on what your budget is, you could also spend half of the break with your friends and the other half with your parents! Discuss potential options with your parents and talk through everything with them.
